Title: REFERENCE SIGNAL TRANSMISSION METHOD AND APPARATUS
Abstract:
The present application provides a reference signal transmission method and device. The method comprises: a sending device converts a reference signal in a frequency domain to a time domain to generate a reference signal in the time domain, the reference signal in the frequency domain comprising a reference signal sequence mapped to a frequency domain resource group, the reference signal sequence being related to a Zadoff-Chu sequence and the length of the reference signal sequence, and the length value of the Zadoff-Chu sequence being greater than the number of minimum time domain resource units comprised in the maximum number of frequency domain resources that are assignable; and the sending device sends the reference signal in the time domain. In the reference signal transmission method in the present application, the PAPR/RCM of a reference signal can satisfy performance requirement, and the number of times of blind detections can be reduced, thereby improving performance of a system.
